Seagate NAS HDD Internals

The Seagate NAS HDD comes in a standard 3.5" form factor with the Seagate's branding on the top of the case.

The bottom of the drive has the PCB with the components turned inward, facilitating thermal dissipation into the case of the drive. The PCB is very compact and smaller than a typical HDD PCB.

Upon removal of the PCB, we note the thermal pad over the controller. This mates with the large metal pad on the bottom of the case. Once we remove the thermal pad the LSI 841281V0 controller dominates the side of the PCB, and a Winbond 64 MB DRAM buffer sets above the controller on the PCB. The SMOOTH chip controls the drive motor.

The drive features a standard 6Gb/s SATA port and features four 1TB platters spinning at 7,200 RPM.
